Answer:

Step-by-step explanation:

to find the length of a diagonal of a square, you would multiply the length of a side by the square root of 2. so 5[tex]\sqrt{2}[/tex] ≈7.07 inches, but since it's the nearest tenth, the answer would be 7.1 inches

Answer:

A fraction is not a whole number but a number in between the whole number .

Step-by-step explanation:

It is a part of a whole. Also, a fraction has two parts of a numerator and a denominator. When the numerator and the denominator can no longer be reduced to any smaller number separately, we get the fraction in its simplest form.

Answer:

18 ft

Step-by-step explanation:

Both triangles shown are congruent.

By the concept of transversal lines and vertically opposite angles, we conclude that the width of the sinkhole is 18 feet.

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

We know when a transversal intersects a parallel line vertically opposite angles are equal and we also know that sides opposite to similar angles have the same length.

∴ The width of the sinkhole is also 18 feet.

Answer:

The better buy is 2 ice cream cones for $3.00

Step-by-step explanation:

Step one:

given

You can buy 2 ice cream cones for $3.00

let us solve for the unit cost

3/2= $1.5 per  ice cream cone

Step two:

You can buy 4 ice cream cones for $7.00

let us solve for the unit cost

7/4= $1.75 per  ice cream cone

The better buy is 2 ice cream cones for $3.00 because a cone is $0.25 less expensive than  4 ice cream cones for $7.00.

Answer:

Negative associaction

Compute the differential for both sides:

4y - 3xy + 8x = 0

→   4 dy - 3 (y dx + x dy) + 8 dx = 0

Solve for dy :

4 dy - 3y dx - 3x dy + 8 dx = 0

(4 - 3x) dy + (8 - 3y) dx = 0

When x = 0, we have

4y - 3•0y + 8•0 = 0   →   4y = 0   →   y = 0

and with dx = 0.05, we get

(4 - 3•0) dy + (8 - 3•0) • 0.05 = 0

→   4 dy + 0.4 = 0

→   4 dy = -0.4

→   dy = -0.1

Answer:

300 cupcakes

Step-by-step explanation:

Okay, the first step is finding 25% of 240, we do this by multiplying .25 by 240. This gets us 60. Then, to get 125% of 240 (since sales dropped 25%), we add 240 and 60, this gets us 300. 300 cupcakes were sold. Another way to do this is 1.25x240. I wanted to explain it more thoroughly, though.

Answer:

  the lines are perpendicular

Step-by-step explanation:

When both equations are written in standard form, they are ...

  y -3x = 5

  3y +x = 2

The coefficients in one of these equations are swapped, and one is negated, relative to the coefficients in the other equation. This means the lines are perpendicular (their slopes are opposite reciprocals).

A graph confirms this relationship.

Answer:

480 units^2

Step-by-step explanation:

5 * 12 =  60

13 * 14 = 182

12 *14 =  168

5 * 14 =  70

            480

The surface area of the given prism will be 480 square units so the correct answer is option C.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

The triangular prism is having 6 surfaces so the surface area will be the sum of the area of all the sides of the prism.

The area of all the sides of the prism will be calculated as follows:-

5  x 12 =  60

13 x  14 = 182

12 x 14 =  168

5  x  14 =  70

The total surface area of the prims will be:-

SA of prism = 60 + 182 + 168 + 70 = 480 square units

Therefore the surface area of the given prism will be 480 square units so the correct answer is option C.

Step-by-step explanation:

Solution:

ATQ,

As we know that,

[tex]\implies\:\:x = \dfrac{mx_{2} + nx_{1}}{m + n}[/tex]

[tex]\implies\:\:x = \dfrac{(a-b)3 + (a+b)2}{3+2}[/tex]

[tex]\implies\:\:x = \dfrac{3a - 3b + 2a + 2b}{5}[/tex]

[tex]\implies\:\:\red{x = \dfrac{5a - b}{5}}[/tex]

Similarly,

[tex]\implies\:\:y = \dfrac{my_{2}+ny_{1}}{m+n}[/tex]

[tex]\implies\:\:y = \dfrac{(a+b)3+(a-b)2}{3+2}[/tex]

[tex]\implies\:\:y = \dfrac{3a+3b+2a-2b}{5}[/tex]

[tex]\implies\:\:\red{y = \dfrac{5a+b}{5}}[/tex]

Hence,

Coordinate of 0 is [tex]\blue{\bigg( \dfrac{5a-b}{5},\:\dfrac{5a+b}{5}\bigg)}[/tex]
